I have multiple (10) if statemnets stacked in a function, and need something like this:
$len=$("#user").val().length;
if($len == 0) { do something and then - stop, exit, break ... whatever)
So, if $len is 0 - do something and - dont check anything more. Just exit from the execution.
You can use return statement but it will take the execution control at end of function and skip all the statements between. or use if-else block or use switch.
if($len == 0) {
do something and then - stop, exit, break ... whatever
return;
)
Use if-else
if($len == 0) {
do something and then - stop, exit, break ... whatever
return;
)
else
if($len == 1) {
do something and then - stop, exit, break ... whatever
return;
)
//repeate if else
Using switch
switch($len)
{
case 0:
//execute code block 1
break;
case 1:
//execute code block 1
break;
case 2:
//execute code block 2
break;
default:
code to be executed if n is different from case 1 and 2
}
Just use this...
$len=$("#user").val().length;
if($len == 0) { return false; }
I am returning false to make sure the event which invoked the function won't run anymore.
